Application filed November 8, 1916. Serial No. 130,204.

To all whom it may concern:

Be it known that I, HENRY O. HALvERsoN,

a citizen of the United States, residing at Burr, in the county of Yellow Medicine and State of Minnesota, have invented certain new and useful Improvements in Animals Traps, of which the following is a specification.

This invention has relation to animal traps, and the nature and objects thereof will be readily apparent to those skilled in the art to which it appertains, in the light of the following explanation of the accompanying drawings, illustrating what I now believe to be the preferred embodiment or mechanical expression of my invention from among other forms and arrangements within the spirit thereof, or the scope of the appended claim.

However, an object of the invention is to provide an animal trap having oppositely disposed entrances, trap doors, and operating mechanism therefor, located at each opening, both however, being operable from a single trip mechanism.

In addition to the foregoing, my invention comprehends improvements in the details of construction and arrangement of parts to be hereinafter described and particularly pointed out in the appended claim.

In the accompanying drawings in. which similar and corresponding parts are designated by the same characters of reference throughout the several views in which they appear;

Figure 1, is a view in side elevation of a trap constructed after the manner of my invention.

Fig. 2, is a view thereof in plan showing the same with the top swung back.

Fig. 3, is a view of the trap in side elevation with the lid removed.

Fig. 4, is a longitudinal section of the trap showing the same in open position.

Fig. 5, is a view similar to the preceding figure showing the trap however, in released or closed position.

Fig. 6, is a transverse vertical section taken on the line 6-6 of Fig. 5, and

Fig. 7, is a view in end elevation of the travn.

ith reference to the drawings 1 indi cates the casin of the trap, in the form of a tube, rectangu ar in cross section. The top portion of the casing is cutaway at both ends asindicated at 2, and vertically oscillatable doors3 are hingedly secured at one of their ends adjacent the cutaway endsof the upper portion of the casing. With reference to Fig. 4, of the drawings, it will be notedthat in open position of the trap, the

trap doors 3 form a substantial prolongation of the top portion of the casing.

Extending transversely of the casing and above each trap door 3 there is provided a cross bar 4, providing in conjunction with similar bars 5 located at the medial portionof the casing, means for supporting bearings fora rock shaft 6 which extends .centrally and longitudinally of the casing above the .the top portion thereof. The ends of the rock shaft 6 are bent at right angles as indicated at 7, while the central portion of the rock shaft between the bearings 5' is pro,-

vided with an arm 8 which in set position of the trap isadapted to extend oppositely and forwardly at an angle. Each trap door is provided upon its top surface with a staple 9 in which the bent ends 7 of the rock shaft are adapted to engage in setposition of. the trap to retain the trap doors raised and in a horizontal plane. The rock shaft is retained in such position by reason of the looped extremity lOofthe arm 8 being disposed over the upper terminal of a vertically reciprocable rod 11, movable in a vertical recess in the front wall of the casing,

and connected at its lower terminal to a tripping platform 12, hingedly secured at its opposite end to the interior of the rear vertical wall of the casing. The said upper terminal of the rod 11 is guided for movement by means of a vertically extending inverted U-shaped bail 13 and a horizontal bail 14. The front wall of the casing is provided with a cover plate 15, which may be removed to expose the vertically reciprocable rod for adjustment thereof.

At each end of the casing there are provided cross bars 16 extending transversely across the upper portion thereof for supporting door securing bails 17, adapted for longitudinaledgebf-thecover i0 ea a iag coacting members 21 secured to the casing to retain the cover in position.

so as to dispose them in a horizontal plane,

and the rock shaft 6 is rocked to bring itsangular ends into engagement with the bails 9 secured to the upper surfaces of the trap doors. secured upon the upper terminal of the rod 11 substantiallj in the inannerasbefofefle I scribed;andthe"trap doors willberetaifie d tudi'n a ll yflof the casing over the top IP01- "tion' thereof, an arm ien tehdiiig fronifthe rock shaftiat' right ang1estheret'o*,.a 1oop on the endof the. arm, a vertically movable trap door Within thef casing a vertically re oiprocable rod connected tothe trap "door, 1
